One of the more common error messages that new Cydia users will come across is the error that says Failed to fetch […] HTTP/1.1 404 Not Found. This is a typical 404 message that you get when you visit a webpage location that no longer exists. Normally, this wouldn’t be a big deal, but it causes an error message to appear in Cydia each time you refresh your list of packages and it attempts to pull data from the non-existent UltraSn0w repo.

You’ll receive an error that states: Some index files failed to download, they have been ignored, or old ones used instead. Yeah, so no big deal, but it’s still a huge annoyance, because this interrupts the stream of refreshing the list of Cydia packages. The fact is that you’ll probably never need to use UltraSn0w, and even if you did, you can always add the repo back to Cydia manually. Read More

Between the rise of third party vendors and the recent change in DMCA policy, the need for iPhone software unlocks is steadily dwindling. But that doesn’t mean that the method is obsolete, as there are still many people out there with older iPhones.

And if you happen to be one of those people, you’ll be happy to know that MuscleNerd has confirmed that Ultrasn0w was quietly updated this week to support iOS 6.1. So if you’re on an eligible device and baseband, you can unlock on the new firmware… Read More

If you’re interested in taking matters into your own hands when it comes to unlocking you iPhone, then you may want to act fast, or else potentially be at risk of being labeled a law breaker. According to a report by Tech News Daily: On Saturday, January 26th, a DMCA exemption expires that made unlocking a phone on your own terms fully legal.

In all actuality, the exemption was nullified back on October 26 (read the final ruling here), but due to a 90 day grace period of sorts, the final expiration date takes place this weekend. Obviously, unlocking is a big subject here at iDownloadBlog, so we’re interested to hear your thoughts on the matter. Bear in mind that it’s not all gloom and doom, though… Read More

The iPhone Dev Team has been mighty busy as of late, updating their popular jailbreak tools with 5.1.1 Untether compatibly using the Rocky Racoon 5.1.1 Untether. The updates include PwnageTool 5.1.1, Redsn0w 0.9.12b1, cinject 0.5.4, and UltraSn0w 1.2.7.

If you’ve already jailbroken your device, and everything is working fine, they suggest, as do we, that you stick with your current jailbreak. If, on the other hand, you’ve experienced problems with tools like Absinthe, then you may welcome the addition of these updated tools from the iPhone Dev Team. Keep in mind that the underlying jailbreak is the same across all tools; they all utilize the Rocky Racoon untether where appropriate; the only difference is the way the exploit is injected.

Take a look inside for notes from the iPhone Dev Team, as well as download locations for the new tools. Read More
